We are in the process of buying a plot of land on the outskirts of a village. It is up a lane which although is adopted is very much a country lane/track that leads up to a wood. As part of the outline planning permission there is a condition that we have to provide a turning circle within our curtilage for service vehicles (even though there is a house further up at the top of the lane). The Highways section of the Local Authority are now saying that not only do we have to provide the turning circle but that we also have to pay for the widening and upgrading of the road to accommodate a service vehicle. Please can you tell me if they are legally able to make a self-builder of a single dwelling pay for such highway improvement costs? This is also on top of them demanding a S106 affordable housing contribution of £15,400 + £1,000 legal costs! Yet the local authorities are supposed to be encouraging self-builders!
